JP 2000-46547 A

  By the way, since the measured gradient of the above-mentioned Patent Document 1 is only displayed on the display unit, the measured gradient data must be separately recorded manually.

  However, the number of measurement points for pipe gradient measurement may reach 1000 or more depending on the site, and when measuring the gradient at such a huge measurement point, the measurement data was manually recorded and measured. Since it was necessary to determine whether all the slopes were within the normal range, managing the measured slope data required a great deal of effort.

  Therefore, there is a demand for a high-pipe slope measuring device that can efficiently and safely perform measurement work on high-pipe piping without using a stepladder or the like, and that can easily manage measurement data. It was.

The present invention has been made in view of the above-described conventional problems, and can easily and safely measure the gradient of piping in high places such as drainage piping such as a ceiling, and also manage measurement data. It is an object of the present invention to provide an altitude piping gradient measuring apparatus capable of performing the above.
Another object of the present invention is to provide a high-level piping gradient measuring device that can measure the gradient of piping in high places, can also manage measurement data, and is compact and portable. To do.

In order to achieve the above object, the present invention

A base portion for fixing the gradient sensor, and a support rod connected to the base portion, and the measurement surface of the gradient sensor at the tip of the support rod is contacted with a high place pipe. A high-level piping gradient measuring device for measuring the gradient of a piping in a high location, provided with a gradient data management device connected to the gradient sensor and capable of taking in gradient data measured by the gradient sensor, and the gradient data management device Means for storing normal range data of a predetermined gradient, and whether or not the gradient data measured by the gradient sensor is within the normal range data. Determining means, display means for displaying the gradient data and the determination result by the determining means together with data for specifying the measurement point of the gradient, specifying the gradient data and the determination result, specifying the measurement point of the gradient Storage means for storing together with the data to be stored, a connection member is fixed to the tip of the support rod, and the base member for supporting the gradient sensor is connected to the connection member. The fixing plate and the bottom plate of the base portion are connected to each other at a predetermined interval by four bolts and nuts, and coil springs are respectively inserted into the bolts, and the bottom plate and the fixing plate are caused by the repulsive force of the coil spring. The base portion is always biased in the direction of separation, whereby the base portion is supported in parallel to the fixed plate, and the fixed plate does not compress the coil spring. Luo along the bolt is slidable in the direction of the bottom plate, altitude, characterized in that by the repulsive force of the coil spring is obtained by slidable in a direction away from said bottom plate along the bolt Consists of a pipe gradient measuring device.

The data specifying the measurement point of the gradient can be, for example, serial number data for each gradient data. Therefore, the slope of the pipe can be measured by holding the support rod and bringing the measurement surface of the gradient sensor at the tip thereof into contact with the pipe at a high place. The measured gradient data is taken from the gradient sensor into the gradient data management device, where it is determined whether or not the gradient data is in the normal range, and the gradient data and the determination result specify the measurement point. It is displayed together with the data, and the gradient data and the determination result can be stored inside together with the data specifying the measurement point. Therefore, for example, it is possible to safely and efficiently measure the gradients of a large number of high-level pipes, and it is possible to efficiently manage the measured gradient data for each measurement point. With this configuration, the gradient sensor can be reliably brought into contact with the pipe by the repulsive force of the coil spring by pressing the support rod in the direction of the pipe while the measurement surface of the gradient sensor is in contact with the pipe. It is possible to measure an accurate gradient even at a high place.

  Second, the gradient sensor sends out the gradient data currently being measured to the gradient data management device based on a data fetch command from the gradient data management device. Each time the is input, a number corresponding to each of the gradient data is given, and the number is used as data for specifying the measurement point of the gradient. Consists of a gradient measuring device.

  Therefore, since the data for specifying the measurement points is set as “number”, the gradient data of a large number of measurement points can be managed efficiently.

  The elastic member can be constituted by, for example, a coil spring (15). If comprised in this way, the said base part can be flexibly rotated with respect to the said support rod with the elasticity of an elastic member, and, thereby, the measurement surface of a gradient sensor can be reliably made to contact piping.

  Hereinafter, the high place piping gradient measuring apparatus according to the present invention will be described in detail.

  FIG. 1 is a view showing an elevated piping gradient measuring device 1 according to the present invention. The device 1 includes a substantially rectangular parallelepiped gradient sensor 2, a gradient sensor support 3 ′ to which the gradient sensor 2 is attached and fixed, It is comprised from the gradient data management apparatus 6 (refer FIG. 6).

  The gradient sensor support 3 ′ is composed of a gradient sensor mounting base 3 for fixing the gradient sensor 2, and a support bar 4 for supporting the base 3 with its tip. As shown in FIG. 3, the absolute level zero set gradient sensor 2 is fixed to the base portion 3, and the measurement surface 2a of the gradient sensor 2 is brought into contact with the drainage pipe 5 from below (see FIG. 5). 2, the gradient of the pipe 5 is measured, and the measured gradient data is displayed on the display unit 18 and is sent from the sensor 2 to the gradient data management device 6 and stored in the management device 6 ( (See FIG. 6).

  The base part 3 for attaching the gradient sensor is composed of a bottom plate 7a made of a rectangular metal plate and a pair of metal opposing side plates 7b, 7b standing upright from both side ends of the bottom plate 7a. Is a substantially “U” shape of the upper surface opening. Cutouts 7b 'and 7b' are formed in the "U" shape from the top to the bottom on the inside of the opposed surfaces of the opposed side plates 7b and 7b. 8 and 8 are oppositely bonded. Further, on the bottom plate 7a, an elastic plate 9 for absorbing shock is bonded to three portions of the bottom plate 7a at both ends and a central portion. And it is comprised so that the said gradient sensor 2 can be fixedly fitted in the attachment space 10 enclosed by the said bottom plate 7a and the opposing side plates 7b and 7b (refer FIG. 3).

  Standing short edges 7 'raised at right angles to the inner side of the plate surface are formed at both edges in the longitudinal direction of the bottom plate 7a and the opposing side plates 7b, 7b. The standing short edges 7', 7 The interval between 'is formed slightly wider than the thickness of the gradient sensor. The width of the bottom plate 7a in the longitudinal direction is slightly longer than the length of one side of the gradient sensor 2 in the longitudinal direction. Therefore, when the gradient sensor 2 is housed in the space 10, the bottom surface 2b of the gradient sensor 2 is placed on the elastic plate 9 of the bottom plate 7a and is opposed to both side surfaces 2c and 2c of the gradient sensor 2. The elastic bodies 8 and 8 of the side plates 7b and 7b are in contact with each other, and the standing short edges 7 'support the peripheral portions of the front and rear plate surfaces 2d and 2d of the gradient sensor 2, whereby the gradient sensor 2 is The space 10 is fixedly stored (see FIG. 3). As shown in FIG. 3, it is preferable that the gradient sensor 2 and the bottom plate 7 a of the base portion 3 are wound and fixed by a fastening belt-like member 58.

  The support rod 4 is a metal pipe having a length of 2 m to 4 m (which can be expanded and contracted depending on the height of the pipe 5) and a cross-sectional diameter of 25 mm in diameter. 12 (coil spring 15, bolt B <b> 2, nut N) is interposed, and the base portion 3 for attaching the gradient sensor is attached.

  The connecting member 11 includes a rectangular plate-shaped metal fixing plate 13 and a pair of metal parallel vertical plates 14 and 14 provided downward from the lower surface side of the central portion of the fixing plate 13. The front end 4a of the support bar 4 is inserted between the parallel vertical plates 14 and 14, and the lateral through holes 4b and 4b (see FIG. 5) are formed through the front end 4a from the outside of the vertical plates 14 and 14. The connecting member 11 is fixed to the distal end portion 4a of the support rod 4 by inserting bolts B1 and B1 into 3) and fastening the other ends of the bolts B1 and B1 with nuts N and N. In the fixed state of the connecting member 11 to the support bar 4, the fixing plate 13 is in a state orthogonal to the support bar 4.

  Then, four through holes 16 are provided in the bottom plate 7a of the base portion 3 for attaching the gradient sensor, and bolts B2 (four pieces) are inserted through the through holes 16 downward from the upper surface of the bottom plate 7a. The coil springs 15 (four pieces) are inserted into the bolts B2 penetrating the lower surface side of the bottom plate 7a, and the lower ends of the bolts B2 are inserted into the four through holes 17 provided in the fixing plate 13, respectively. With the coil spring 15 compressed, the base 3 for attaching the gradient sensor is mounted on the fixed plate 13 by screwing nuts N into the bolts B2 from the lower surface of the fixed plate 13.

  Thereby, as shown in FIG. 3, the base portion 3 for attaching the gradient sensor can be fixed to the tip portion 4 a of the support rod 4. At this time, the bottom plate 7 a of the base 3 and the fixing plate 13 are parallel to each other, and the fixing plate 13 is orthogonal to the support bar 4. Further, the fixing plate 13 and the bottom plate 7a of the base portion 3 are urged in a direction away from each other (reverse direction) by the repulsive force of the coil spring 15, and the fixing plate 13 is in this repulsive state. On the other hand, the base portion 3 is supported in parallel (horizontal). Therefore, the fixed plate 13 can slide in the direction of the bottom plate 7a along the bolt B2 while compressing the coil spring 15, and in a direction away from the bottom plate 7a along the bolt B2 by the repulsive force of the coil spring 15. It is slidable.

  That is, as shown in FIG. 5, when the measurement surface 2a on the upper surface of the gradient sensor 2 is in contact with the lower surface of the drainage pipe 5, when the support rod 4 is gripped and pressed upward, the coil spring 15 is compressed. As a result, the distance between the fixed plate 13 and the bottom plate 7a is reduced, whereby the measuring surface 2a of the upper surface of the gradient sensor 2 can be brought into contact with the lower surface of the pipe 5 by the repulsive force of the coil spring 15. It is configured as follows. When the gradient sensor 2 is in contact with the pipe 5, the center axis C1 of the pipe 5 and the measurement surfaces 2a and 2a of the gradient sensor 2 are parallel to each other, so The gradient M of the pipe 5 with respect to G (see FIG. 16) (inclination angle of the central axis C1 of the pipe 5 with respect to the reference horizontal plane G) can be measured.

  Further, as shown in FIG. 5, the base portion 3 for attaching the gradient sensor is fixed to the rotation center axis C3 (line perpendicular to the paper surface) perpendicular to the center axis C2 of the support bar 4. It is configured to be able to be slightly rotated and inclined with respect to the plate 13 in the rotational direction (the directions of arrows A and B in FIG. 5), and the central axis C1 of the pipe is orthogonal to the central axis C2 of the support bar 4. In this case, the oblique angle is absorbed by the rotation of the base portion 3 so that an accurate gradient can be measured.

  Next, the structure of the gradient sensor 2 will be described based on the functional block diagrams of FIGS. 7, 8, and 14.

  As shown in FIGS. 1 and 2, the gradient sensor 2 has a substantially rectangular parallelepiped box shape narrow in the width direction, and the measurement surface 2 a on the upper surface of the sensor 2 is used as an object to be measured such as a pipe 5. By bringing them into contact with each other and making the angle of the object to be measured parallel to the angle of the measurement surface 2a, the inclination of the object to be measured with respect to the reference horizontal plane G (for example, the inclination angle θ with respect to the reference horizontal plane G or the reference horizontal plane G per 1 m) And a function of measuring a gradient M [mm / m] from FIG. 16B). Since the measurement surface 2a and the bottom surface 2b of the gradient sensor 2 are parallel to each other, the gradient of the measurement object can also be measured by placing the gradient sensor 2 on the measurement object with the bottom surface 2b. Can do.

  As shown in FIG. 7, the gradient sensor 2 includes a sensor unit 2 ″ (see FIG. 14, gradient measuring means 40) including a sensor body 2 ′ (see FIG. 8), and a display unit 18 that displays measured gradient data and the like. (FIG. 14, display means 41), operation section 19 for performing various operations (power button 60, absolute horizontal zero set button 61, mode setting button 62) (FIG. 14, input means 42), FIG. 10 and FIG. A memory 20 ′ in which a control program 20 composed of the operation procedures shown is stored, a memory 21 (FIG. 14, storage means 43) for storing various data such as measured gradient data, and a CPU 22 for executing the control program 20 And an input / output interface 23 (FIG. 14) for outputting gradient data measured based on a data fetch command from the gradient data management device 6 described later to the management device 6. Data capture command recognition unit 44, which comprises a data output unit 45).

  The sensor body 2 'has the configuration shown in FIG. The sensor body 2 'is provided with two fixed electrodes 25a and 25b in a sealed case 24, and a light disc 26 of 1 g or less is formed with a pendulum structure with very little friction between the fixed electrodes 25a and 25b. It is supported. The center main body 2 'is arranged such that the disk 26 is positioned at the neutral position in FIG. 8A in a state where the gradient sensor 2 is placed on a horizontal surface with the measurement surface 2a or the bottom surface 2b. Further, it is fixed in the gradient sensor 2.

  Therefore, when the gradient sensor 2 is inclined and the measurement surface 2a is inclined from the horizontal plane, the lightweight disk 26 in the case 24 is inclined according to the inclination of the measurement surface 2a, as shown in FIG. 8B. Therefore, the sensor section 2 ″ (FIG. 14, data conversion means 46) changes the capacitance CA between the disk 26 and the fixed electrode 25a at this time, and the capacitance between the disk 26 and the fixed electrode 25b. In addition to detecting changes in CB, these capacitance changes are converted into electrical signals and sent to the CPU 22. The case 24 of the sensor body 2 'is completely sealed with an air damper 24'. Therefore, it has a structure that is not affected by temperature changes as much as possible.

  The CPU 22 is based on the control program 20, and the reference gradient data S (usually the gradient θ = 0 degrees or M) corresponding to the reference horizontal plane G (normally the horizontal plane having an inclination of 0 degree) stored in the memory 21 in advance. = 0 [mm / m]) (FIG. 14) and the electrical signal (measured value) from the sensor unit 2 ″, the gradient data (inclination angle θ with respect to the reference horizontal plane G or the reference horizontal plane G On the other hand, a gradient M [mm / m] per meter is calculated, and the gradient data is displayed on the display unit 18 and stored as gradient data D (see FIG. 14) in the memory 21. Further, the CPU 22 (data The take-in command recognizing means 44) receives the gradient data take-in command from the gradient data management device 6 based on the control program 20, and outputs the currently measured gradient data to the input / output interface. The data is output to the face 23 and the data is sent to the gradient data management device 6.

  When the gradient sensor 2 is used, it is necessary to perform absolute horizontal zero setting in advance. That is, the gradient sensor 2 is installed on the reference horizontal plane G (FIG. 16A), the gradient of the reference horizontal plane G is measured, the gradient of the reference horizontal plane G is measured as the reference gradient data S, and the reference gradient Data S is stored in the memory 21. Therefore, after the reference gradient data S is measured, difference data from the reference gradient data S is output (displayed) as gradient measurement data (gradient data). The absolute horizontal zero set is basically unnecessary after setting once. In addition, after performing the absolute horizontal zero set, the sensor unit 2 ″ of the gradient sensor 2 sets the gradient data of the measurement surface 2a at the position where the sensor 2 is placed at intervals of several seconds in the power-on state. Thus, the CPU 22 is configured to output the gradient data currently being measured to the input / output interface 23 when there is the data capture command.

  Next, the gradient data management device 6 for managing the gradient data measured by the gradient sensor 2 will be described based on the functional block diagrams of FIGS. 9 and 15.

  The gradient data management device 6 is constituted by a so-called notebook personal computer (hereinafter referred to as “personal computer”) in which a control program 27 shown in FIG. 12 is stored. That is, the data management device (personal computer) 6 has a plurality of connectors C (for example, an RS232C connector Ca, a USB connector Cb, and other data connectors Cc) for connecting to an external device such as the gradient sensor 2. It is configured to be able to exchange various data with an external device via the external input / output interface 28 (FIG. 15, data fetching means 50). Specifically, any of the connectors Ca to Cc and the gradient sensor 2 are connected by a cable K (here, the cable K is connected to the USB connector Cb), and the gradient sensor 2 is connected. The gradient data measured in (1) can be taken into the management device 6 via the external input / output interface 28 from the connector Cb.

  In the gradient data management device 6, reference numeral 29 denotes a bus. The input / output control device 30, the CPU 31, the internal memory 32 in which the control program 27 is stored in the bus 29, and the external memory 33 such as a hard disk (FIG. 15, storage means 51 ) Is connected. The control program 27 executes a gradient data fetching operation and the like according to the operation procedure shown in FIG. 12, and the CPU 31 assigns a gradient data numbering operation input from the gradient sensor 2 according to the control program 27 (FIG. 15, number). Appending means 52), determination operation (FIG. 15, determination means 53), storage operation (FIG. 15, storage control means 54), display operation (FIG. 15, display control means 55), and the like. The input / output control device 30 is connected to a display 35 (FIG. 15, display means 56) and an input device 34 (FIG. 15, input means 57) such as a keyboard.

  The external memory 33 stores normal range data L (for example, L = 9 [mm / m] to 10 [mm / m]) having a preset gradient for performing the determination operation. Yes.

  An example of a screen displayed on the display 35 of the gradient data management device 6 is shown in FIG. On the above screen, there are a measurement number display field “No” as a serial number for specifying the measurement location, a gradient data display field “inclination (mm / m)”, and a display field “determination” for displaying the determination result. Yes, a capture button 65 for capturing gradient data, a save button 66 for storing gradient data and the like, and an invalid button 68 for invalidating the gradient data when the determination result is “×”. In addition, a clear button 69 for erasing data, an end button 67 for ending the program, and a normal range 70 of the set gradient are displayed.

  Since this invention is comprised as mentioned above, the operation | movement which measures the gradient of a high place drainage piping using the high place piping gradient measuring apparatus of this invention is demonstrated next.

  First, as preparation, absolute horizontal zero setting of the gradient sensor 2 is performed (see FIG. 10). First, the gradient sensor 2 alone before mounting is placed on the reference horizontal plane G (see FIG. 16) on the base 3 for mounting the gradient sensor (see FIG. 16), and the power button 60 (FIG. 14, input) of the operation unit 19 of the sensor 2 is mounted. The means 42) is turned on to turn on the sensor 2 (FIG. 10P1). Then, the power supply means 47 (FIG. 14) of the sensor 2 supplies power to each part in the sensor 2, and the sensor 2 enters an operating state (P1 in FIG. 10).

  Thereafter, when the absolute horizontal zero set mode is set from the absolute horizontal zero set button 61 (input means 42) of the operation unit 19 (P2 in FIG. 10), the CPU 22 displays the gradient data (sensor unit 2 ″) measured by the gradient sensor 2 at that time. The gradient data being output) is read to measure the gradient (FIG. 10P3), and the gradient data is stored in the memory 21 as the reference gradient data S and displayed on the display unit 18 (FIG. 10P4). Since the reference gradient data S is set, it is possible to measure the gradient with respect to the reference gradient data S. The reference gradient data S can be used even if the power of the gradient sensor 2 is turned off (P5 in FIG. 10). Retained.

  Next, the gradient sensor 2 is fitted and attached to the base 3 for attaching the gradient sensor as shown in FIG. 3, and the concave portion 2a ′ at the center of the sensor 2 and the bottom plate 7a are wound and fastened by a belt-like member 58. Then, the gradient sensor 2 is fixed to the base portion 3.

  In the gradient data management device 6, the normal range data L of the gradient (for example, 9 [mm / m] to 10 [mm / m]) is input in advance from the input device 34 of the management device 6 into the device 6. It is assumed that the normal range data L is stored in the external memory 33 (storage means 51) of the management device 6.

  Then, a connector (for example, an 8-pin connector) of the input / output interface 23 of the gradient sensor 2 and a USB connector Cb of the gradient data management device 6 are connected by a cable K, and the lower end portion of the support rod 4 is gripped. The gradient sensor 2 at the tip 4a is lifted upward in a substantially vertical direction, and as shown in FIG. 6, the measurement surface 2a on the upper surface of the sensor 2 is brought into contact with the lower surface of the drainage pipe 5 disposed on the ceiling.

  When the measurement surface 2a of the gradient sensor 2 comes into contact with the lower surface of the pipe 5, the support rod 4 is further lifted slightly upward, and the coil spring 15 of the base portion 3 for attaching the gradient sensor is compressed. The measurement surface 2 a of the gradient sensor 2 is reliably brought into contact with the lower surface of the pipe 5 by the repulsive force of the coil spring 15. Thereby, the said side fixed surface 2a of the said gradient sensor 2 can be made into a parallel state correctly with the central axis C1 of the said piping 5. FIG.

  The gradient sensor 2 measures the gradient in this state, that is, the gradient of the pipe 5 (P1 and P2 in FIG. 11). Specifically, in a state where the measurement surface 2a of the gradient sensor 2 is in contact with the lower surface of the pipe 2, the CPU 22 (FIG. 14, data conversion means 46) is connected to the sensor unit 2 ″ (FIG. 14, gradient measurement means 40). ) To read the electrical signal corresponding to the gradient input and compare it with the reference gradient data S to calculate the current inclination angle (gradient (inclination) data) of the pipe 5 (FIG. 11P2), and the CPU 22 (FIG. 14). The data output means 45) displays the calculated gradient data on the display unit 18 (FIG. 14, display means 41) (FIG. 11P3).

  Thereafter, the operator presses the capture button 65 (FIG. 13) on the display 35 of the gradient data management device 6 (clicks with the mouse pointer, etc.) (FIG. 12P1). Then, the CPU 31 (FIG. 15, data fetching means 50) of the management device 6 sends a data fetch command to the gradient sensor 2.

  Then, the CPU 22 (FIG. 14, data capture command recognition means 44) of the gradient sensor 2 detects this (FIG. 11P4), and the CPU 22 (FIG. 14, data output means 45) detects the gradient data M1 currently measured. Is sent to the gradient data management device 6 through the input / output interface 23 (FIG. 11P5).

  Then, the gradient data M1 is input to the gradient data management device 6 via the cable K (P2 in FIG. 12). The CPU 31 (FIG. 15, numbering means 52) assigns the measurement number “1” as “data specifying the measurement point of the gradient” to the acquired gradient data M1 (FIG. 12P3) and associates it with the gradient data M1. Memorize temporarily. Next, the CPU 31 (FIG. 15, determination means 53) determines whether or not the fetched gradient data M1 is within a normal range (FIG. 12P4).

  The CPU 31 (determination unit 53) reads normal range data L [mm / m] of a gradient set in advance in the external memory 33 (FIG. 15, storage unit 51), and the gradient data M1 enters the normal range. It is determined whether or not (FIG. 12P5). If the gradient data M1 is within the normal range, it is determined as “normal” (FIG. 12P6), and if the gradient data M1 is not within the normal range, “abnormal” is determined (FIG. 12P7). ).

  Subsequently, the CPU 31 (display control means 55) displays the measurement number “1” and the gradient (tilt) data “M1 [mm / m]” on the display 35 (FIG. 15, display means 56). If the determination result is “normal”, “◯” is displayed in the determination display column, and if the determination result is “abnormal”, “x” is displayed in the determination display column (see FIG. 12P8, FIG. 13). ).

  Thereafter, when the operator presses the save button 66 on the display 35 (clicking with the mouse pointer or the like) (FIG. 12P9), the CPU 31 (FIG. 15, storage control means 54) specifies the measurement number (measurement point of the gradient). Data) “1”, gradient (slope) data “M1”, and determination result “◯” or “x” data are stored in the external memory 33 (FIG. 15, storage means 51) (FIG. 12, P10, P11).

  With the above operation, the measurement of the gradient data M1 of the pipe at the first measurement location is completed. Next, the operator moves below the drain piping 5 at the second gradient measurement location, and the drain piping. 5, the support rod 4 is held and the gradient sensor 2 is lifted toward the bottom surface of the pipe 5 in the same manner as described above, and the measurement surface 2 a of the gradient sensor 2 is pressed against the bottom surface of the pipe 5. Then, the gradient of the second pipe 5 is measured (FIG. 12P13 to FIG. 12P1). Thereafter, the gradient of the drainage pipes at a plurality of locations can be measured one after another by the same procedure as described above.

  That is, when the measurement surface 2a of the gradient sensor 2 is pressed against the bottom surface of the second pipe 5, the gradient data of the second drain pipe 5 is measured (FIGS. 11P2 and P3). When the data acquisition button 65 of the gradient data management device 6 is pressed (FIG. 12P2), the gradient data M2 is sent from the gradient sensor 2 to the management device 6 (FIGS. 11P4 and P5). When the management device 6 receives the gradient data M2 (FIG. 12P3), it assigns a measurement number (data for specifying a measurement point of the gradient) “2” to the gradient data M2 (FIG. 12P3), and the gradient is in the normal range. (P4 to P7 in FIG. 12), the gradient data M2 is displayed together with the measurement number and the determination result (FIG. 12P8), and based on the pressing operation of the save button 66 by the operator, The gradient data M2 is stored in the external memory 33 together with the measurement number “2” and the determination result “◯” or “×” (FIGS. 12P9 to P11).

  In this way, the gradient can be measured simply by sequentially pressing the measurement surface 2a of the gradient sensor 2 against the bottom surfaces of the plurality of pipes 5 while moving the measurement location. , Data for specifying each measurement point, gradient data M1, M2, M3... For each measurement point, and determination results for each measurement point can be stored sequentially. And gradient data can be managed very efficiently.

  In the present invention, as described above, the measured gradient data M1 and the like of the high-level piping 5 is taken into the gradient data management device 6 from the gradient sensor 2, and the management device 6 determines whether or not the gradient data is in the normal range. Since the gradient data and the determination result are displayed together with the data for specifying the measurement point and can be stored in the inside, the gradient of the high-level piping at, for example, 1000 or more locations can be safely and efficiently performed. The measured gradient data can be managed efficiently for each measurement point.

  In addition, the gradient sensor support 3 ′ including the support rod 4 can safely and reliably measure the gradient of the piping 5 at a high place without using a stepladder or the like.

  Further, the gradient sensor 2 can be reliably brought into contact with the high place pipe 5 by the repulsive force of the coil spring (elastic member) 15, and an accurate gradient can be measured even in the high place pipe 5.

  Further, since the gradient data management device 6 can be constituted by a portable personal computer or the like, the gradient sensor support 3 'and the gradient data management device 6 as a whole can be made portable and can be carried. A convenient device is realized.

  The altitude pipe slope measuring device of the present invention is suitable when it is necessary to measure the slope of a large number of pipes, such as the slope of drainage pipes installed on the ceiling surface of commercial buildings, etc. It can be widely used for the gradient measurement of piping at high places.
